Monster hunter Dean Winchester (Jensen Ackles) embraces his dark side in the Supernatural season premiere “Black.” Dean’s brother, Sam (Jared Padalecki), believes he’s been possessed by a demon but Dean is the demon, a Deanmon. His soul becomes twisted after he receives the mark of Cain along with the First Blade used to kill Abel. He even stars hanging out with the King of Hell, Crowley (Mark Sheppard).

“It’s less about him being demonic and evil and sinister, and it’s much more about him being carefree and jovial and doing things regardless of the consequences,” Ackles told Entertainment Weekly. “He could give two sh-ts of what anybody thinks, including Crowley, which ends up being a bit of a situation.”

That means giving into guilty pleasures like karaoke. He gives his drunken rendition of “I’m Too Sexy” by Right Said Fred and “Imaginary Lover” by Atlanta Rhythm Section.

Deanmon is booed off the stage but cheered on by his latest sexual conquest Ann Marie (Emily Fonda). In fact, her only complaint is “that thing with the thing” was too long making her late for work. While she hurries to get dressed, Dean basks in his nudity (in Crowley’s bed). In real life, Ackles is not too sexy for his shirt.

“Right said Fred gets me every time! Haha,” he tweeted. “You go #Deanmon now put a shirt on. What the hell?”

Just like Right Said Fred, Deanmon won’t be around forever Ackles assures fans. Dean will be saved by a “miraculous event.” Sam seeks help from their angel friend Castiel (Misha Collins), who has his own problems. Cas is dying after losing his grace.

“There’s a bit of a shelf-life on his grace,” Ackles explained. “It’s a massive issue, and of course, Cas being the martyr that he is, he’s going to put that aside and do what he can to help Sam fix Dean. That being said, yeah, the issue of his grace fading is going to need to be addressed, and it’s going to need to be addressed very quickly. I will say that it gets addressed, but it does not get cured.”
